Specification of Letters Patent.

Patented Yov. 14, 1911.

Application filed December 10, 1910. Serial No. 596,674.

To all whom it may concern:

Be it known that I, GEORGE L. Hess, a citizen of the United States, residing at La Junta, in the county of Otero, State of Colorado, have invented certain new and useful Iln rovements in Flumes; and I do hereby dec are the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to flumes and particularly to that type employed in irrigation.

' The object of the invention resides in the provision of a lural section flame of the character name which includes improved means for securing the sections together in a water-tight manner and which at the same time will ofl'er the least resistance to the flow of water through the flume.

A further object of the invention resides in securing certain of thesections of the flume to ther in a water-tight manner so as to. permit the sections so connected to move lon 'tudinally with respect to each other wit out destroyin such water-tight connection and thereby a low for the expansion and contraction of the sections of the fiume and obviate the possibility of breakage or disarrangement of parts due to such expansion and contraction.

With these and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the I appended claims.

In describing the invention in detail, reference will had to the accompanying drawings, wherein like characters of refer ence denote corresponding parts in the several. views; and in which,

Figure 1 is a detail perspective view of a a "portion of a fiume constructed-in accordance with .the inventionyFig. 2, a longitudinal section of Fig. '1; Fig-3, a transverse section through one of the non-yieldable connectionsbetween the flume sections; Fig. 4, a detail perspective View of the yielding connecting' member emplgyed between certain of the sections of the ume; and, Fig. 5 a detail perspective" view of one of the wed ingshoes employed in the non-yielding con-' nections bctwqglcthe flurne sections.

carrierbeam 24 at opposite endso Referring to the drawirr the portion of the flumo illustrated in Fi 1' is shown as comprising a plurality of s ctions 10, 11, 12, 13, 14 and 15. The sectior 10 is secured to the section 11 by means 0? a non-yielding connection. This connectic u is produced by forming one end of the sect on with a groove 16 and a resultant rib 17 ex ending throughout the entire transverse e :tent of the section 10. The end of the se :tion 11 adjacent the section 10 is likewise formed with a groove 18 and a resultant rib 19 extending throughout the entire trar sverse extent of the section 11. The ribs 1F and 19 are de pressed inwardly as at 24 and 21 respectively, for a purpose that i in presently appear. In connecting the st ctions 10 and 11 together, the rib 17 of t 1e section 10 is seated in the groove 18 of t 1e section 11 and the depth of-thegroove 15 is such that the inner faces of the sections 10 and 11 will be located in the same cylindrical plane.'

minals 23 pass through the ends of the carrier beam 24 which extem s across the sections of the flume. Nuts 2 i mounted on the threaded terminals of the :a-rrier rod serve when inanipulated to draw" the carrier rod firmly into the depression 21 of the rib 19, the seating of said carrier: n this depression serving to secure the sum 2 against lateral displacement. The.inner (lamping member B comprises an arcuate bar 2 6 conforming to the configuration of the g roove 16 so that when said member is seat( (1 in said groove the inner face thereof will register with and form a continuation of ti e inner faces of the inner sections 10 and L1. The ends of.

the in-ner clamping memh 2r B enga e the said beam respectively so that vhen the nuts 25 are manipulated to draw tie carrier rod 22 into the depression 21, th inner clamping member B is forced into tie groove 16 and an eiiicient. clamping act on between the inner and outer clamping 1 iembers A and B had. In order to orce clamping member B outw irdly during the 1 clamping operation and bus equally disthe ends of the tributingthe force thereof, there is provided -a pair of corresponding wedging shoes 27 mounted respectively on the terminals of the carrier rod 22'beneath the carrier beam 24; Each 'of these wedging shoes is provided on its underfface with an extension 28 having a cam face 29. This face is positioned for engagement with the inner edge of the ad acent end of theclamping member B. so that "tribute-the force of such clamping. action evenlyQ 'The sections 12 and 13 and likewise, the sections 13 and 1.4 are connected to each other respectively in a manner similar:

to the sections and 11 and adetailed de-' scri tion thereof will therefore-be omitted.-

lie disarrangement of the various secas the nuts 25 are manipulated during the clampin action .a wedging efi'ectwil member B outwardly and as a result distions as the result of expansion and contraction is obviated by the following structure.

The sections 11 and 12 are arranged with their adjacent ends overlapped, the end of the sectlon 11 being disposed against the inner face of the section 12. Surrounding.

the junction of the sections 11 and 12 is a connecting member C which is substantially- Vshaped and includes the angular arms 30:

and 31, the free ends of which terminate in laterally extending portions 32 and 33 respectively which are disposed in turn res'pectively against the outer faces of the. sections 12' and 11. The laterall I extending portion 32 is then riveted to t e 'section' 11 to produce a'water-tight joint, while the laterally extending. portion 33 is similarly riveted to the outer face of the section 12. The arms 30 and 31 are shown soldered and riveted to other at their meeting point,

although t e connecting member C may be" constructed with facillty out of a single piece .'of material. The arms 30 and 31 possess suflicient resilienc to permit the longitudinal movemento the sections 11 and 12 with respect to each other under the influence of expansion and contraction without in any nature disturbing the watertight connection between said sections formed by the member C. The sections 14 and- 15 are connected to each other in a manner similar to the sections 11 and 12, and a detailed descrigtion thereof. will therefore be omitted. y the use of the connectin member C it will also be apparent that t e flume can be bent laterally and also elevated or lowered. at different points j in its extent without in any mannerv disturbing the water-tight connections,

will be' apparent From the foregoing, it

' that there has been constructeda flume which has a very small co-efiicient of friction resultmg m an increased carrying capacity of the flume, and further' sai flume may respond to expansion and. conbe "produce to force the ends of the clamping traction due to changes in temperature without in any manner injuring or disarranging the. arts thereof.

at is claimed is 1. The combination of a pair offlume sections having their adjacent ends. formed with interior grooves and resultant exterior ribs and disposed in overlapping relation with. the rib of on'esection seated in the roove of the other section, the groove of the first named-section being of-less de th-than the groove of the second name section whereby the-inner faces of said sections are.

sions, and the groove of the first named sec tion being of less depth than the groove of the second named section whereby the faces of said sections are disposed in thesame plane, and inner andouter clamping mcin-f here, the. inner clamping membei"- seated in the groove of the first named" tion and having inner face positioned form a continuation of the inner said sections and the outerclam i'ng' nr. ber bei g seated in the depression (if-the second namedsection.

' 3. The combination of a pair of flume sections having overlapped ends, and an angular member conforming to the configuration of the sections and ,having yield v mg arms, the free 'ends of which are respectively secured to said' sgftions so that said angular member covers the joint be tween the sections and the latter close communication between the interior of the sections and the space between the arms of the angular member. l 4. The combination of a pair of flume sections having their adjacent end portions overlapped and provided with alternate depressions and eminences which interlock, an

inner clamping bar disposed againstthe inner face of the inner overlapped portion.

and conforming to the general shape thereof, and an outer clamping bar disposed against the outer face of the outer voverlapped portion in dampingfrelation to-the inner clamping bar.

5. The combinationfof a pair-of flume sec-,

tions having; their adjacent ehd portions overlapped and provided with alternatede pressions andeminences which interlock,

an inner'cla'mping bar disposed against the" and conforming .to the general shape thereinner face of the inner overlapped portion terlock, an inner clamping bar disposed in a groove of, and against the inner face of the inner corrugated overlapped end, an outer cla nping bar disposed in a groove of,

and against the outer face of the outer corrugated overlapped end, in clam ing relation to the inner clampin 1 var, an a spreading shoe mounted on cue 1 end of the outer clamping bar engaging n spective ends of 20 the inner clamping bar and adapted to force 'the ends of the inner c1 imping bar outwardly during the clampir g oiperation.
